    3039Current status:
     40* All test pass except for:
     41  sage -t  "devel/sage/sage/geometry/lattice_polytope.py" (apparently caused by categories, though I don't see how)
     42  sage -t  "devel/sage/sage/structure/sage_object.pyx"    (unpickling of old stuff)
    3143
    3244* Documentation:
    … …  
    4254
    4355* Categories:
    44   - All the mathematical categories of Axiom and MuPAD
    45   - EnumeratedSets         (with example)
    46   - Semigroups             (with example, basic methods, subquotients)
    47   - FiniteSemigroups       (with example, cayley graphs, basic representation theory, ...)
    48   - ModulesWithBasis       (with example, morphisms)
    49   - HopfAlgebras & friends (with example)
     56  - All the mathematical categories of Axiom and MuPAD (Courtesy of Teresa Gomez Diaz)
     57  - (Infinite/Finite)EnumeratedSets (with example) (Courtesy of Florent Hivert)
     58  - Semigroups                      (with example, basic methods, subquotients)
     59  - FiniteSemigroups                (with example, cayley graphs, basic representation theory, ...)
     60  - ModulesWithBasis                (with example, morphisms)
     61  - HopfAlgebras & friends          (with example)
    5062  - Cleanup:
    5163    - Have unique representation by default (no need to inherit from Category_uniq)
    … …  
    6476  - Adds morphisms for some categories
    6577  - Some general infrastructure
     78  - Hom:
     79    - Simplification of the logic. Hopefuly completely compatible.
     80    - X._Hom_(Y, category) may now return NotImplemented
     81    - failed attempt at using cached_function (to be pursued)
     82  - Systematic use of category = ... instead of cat =
     83    This may be backward incompatible.
    6684
    6785* Generic test framework
    6886  - Functional, final design clear, needs cleanup (2/3 hours)
    6987
    70 * Combinatorial free modules
    71   * Have unique representation
    72 
    7388* Reorganization of the Sage library to start using the category framework:
     89  * Combinatorial free modules
     90    * Have unique representation, use coercion, are more robust
     91    * Improved _repr_
     92    * Handle combinatorial classes that can't be sorted as indices
     93  * Groups:
     94    * AbelianGroup_class.__init__ was missing a call to Groups.__init__
     95    * NAME CONFLICT: AbelianGroups are *not* in AbelianGroups()
     96      With the current conventions:
     97       - AbelianGroups is about additive abelian groups
     98       - AbelianGroup  is about multiplicative abelian group
     99    * Support for Group.__init__(category = ...)
    74100  * Fixed some import loops
    75101  * Added temporary list() methods to:
    … …  
    80106    - ParentWithMultiplicativeAbelianGens
    81107    They should eventually be inherited from the EnumeratedSets() category
    82   * ...
     108  * Added sage.sets.finite_enumerated_set
    83109
    84110* Todo:
    … …  
    95121    * class.an_instance() ?
    96122    * all_weakly_super_categories -> ?
     123    * move all examples in examples/
     124    * AbelianGroups() versus CommutativeGroups()
     125
    97126  * Category graph picture
    98127
    … …  
    112141* Discussion:
    113142  * Defining new inline operators, at least within the sage interpreter
